and endwise of a base-board of a wall of a room to be heated by saidheater.

One object of this invention is to produce a strong and durable radiator or heater of the character indicated which comprises a substantially horizontally arranged receptacle having a heating-fiuid-receiving interior chamber extending endwise of the receptacle.

Another object is to use sheet-metal in the formation of said receptacle, and to adequately reinforce the receptacle externally at points spaced endwise of the receptacle.

Another object is to so construct my improved radiator or heater that the bottom of the hereinbefore mentioned chamber is spaced upwardly from the floor on which the heater is adapted to stand, and more especially to provide the receptacle, adjacent said bottom and externally of said chamber, with two spaced opposite members which extend below said bottom and endwise of the receptacle, and to supply air from the outer sides of one or both of said spaced members to the space formed under said bottom between said spaced members.

Another object is to render my improved radiator or heater suitable for the use of steam or hot water as a heating fluid, and

i to render the heater reversible side for side a top plan and a bottom plan. Fig. 4 is an end view. Fig. 5 is a vertical transverse section taken along the line 55 in Fig. 1. Fig. 6 is a central vertical longitudinal section taken along the line 5 5 in Fig. 2. Fig. 7 is a horizontal section taken along the line 77 in Fig. 6. Fig. 8 is a transverse vertical section taken along the line 88 in Fig. 6, looking outwardly. Figs. 5, 6, 7 and 8 are drawn on a larger scale than Figs. 1, 2, 3 and 4. I

My improved radiator or heater comprises a substantially horizontally arranged receptacle which is oblong in plan and has a heating-fluid-receiving lnterior chamber 10 extending endwise and substantially from end to end of the receptacle. Said chamber is shown as having a top wall which (see Fig. 6) curves outwardly in cross-section and is formed by the top or central longi tudinal member 12 of a substantially horizontally arranged inverted-trough-shaped metal section preferably composed of sheetmetal and extending from end to end of the receptacle and having two spaced opposite side members 13 which are connected together by the member 12 and arranged to form opposite upright longitudinal or side walls respectively of said chamber.

The chamber 10 has a bottom 15 arranged between and extending endwise of the side members 13 and spaced, preferably from end to end, upwardly from the bottom edges of said side members, and said chamber has two end upright transverse or end. walls 16 formed at o posite ends respectively of said bottom and arranged between the side members 13. The bottom 15 and the end walls 16 preferably comprises a sheet-metal section which is interposed between the side members 13 and bent and disposed as required to form said walls and said bottom.

The end walls 16 extend and conform to the top wall 12, and the section forming the end walls and the bottom 15 is brazed or otherwise suitably secured, at and from end to end all of its edges, to the hereinbeforementioned inverted-trough-shaped section, so as to form fluid-tight joints between said sections. 7

The side members 13 of said invertedtrough-shaped section (see Figs. 1, 5, 6 and 8) extend, as at 1'1 as already hereinbefore indicated,.-below the bottom 15 from end to end of the receptacle, and therefore the receptacle is provided, adjacent said bottom and externally of the chamber 10, with two spaced members 17 extending below said bottom and endwise of the receptacle. The side members 13 (see Figs. 3, 6 and 7.). prefer.-

ably extend, asters, somewhat outwardly tom and preferably arranged centrally between the portions 17 of the side :members 13. VSaid pi-pe-connection (see Fig. 5) registers with a hole 19 formed in and extending vertically through the bottom 15- and is,

therefore, placed in communication with the chamber 10, and said bottom slopes from each end of the receptacle downwardly toward saidpipe-connection. "Each end'wall '16 (see Figs. 1, d, and 8) is provided, at the outer side .of its upper end portion, with an internally screw-threaded pipe-connection 21 brazed or otherwise secured to said wall and preferably arranged centrally between the sides of the receptacle, and said pipe-connection (see Figs. 6 andS) registers with a hole 22 formed in and extending laterally through saidwall, and therefore said pipe-connection is placed in communication with the chamber 10. When hot water is to be used as a heating fluid in my improved radiator or heater, hot-water-feeding pipes (not shown) are placed in connnunication, at the pipe-connections 21 of the nd walls 16,.with the chamber 10, and the pipe-connection '20 is placed in communication with a drain-pipe (not shown). When steam is to .be employed as a heating .fiuid in'the heater, the pipe-connections 21 are plugged in any approved 'manner, and the pipe-connection 20 is placed in communication with a pipe (not shown) adapted tobe employed both in supplying steam to the chamber 10 and in draining said chamber "of water resulting from the condensation of vapor in the chamber.

The hereinbefore-mentioned invertedtrough-shaped section'and the bottom 15'are reinforced at points spaced endwise of the receptacle between the pipe-connection 20 and each end of the receptacle, and highly practical reinforcingmeans for the receptacle comprises two strong metal straps or reinforcing members arranged at opposite ends respectivelyof the receptacle and two strong metal straps or reinforcing members C arranged between each end reinforcing member B andthe pipe-connection 20. Said reinforcing members 13 and G are spaced endwise of the receptacle, and each of said reinforcing members embraces the invertedtrougth-shaped section above the bottom 15 and embraces the lower portionsl'Z of the side members 13 of said section below said bottom and participates in the formation of supporting means for the receptacle. Preferably each .of said reinforcing members (see Figs. 8 and 9) has a portion 23 straddling and embracing the invertedtrough-shaped section above the bottom 15, and each reinforcing member, below said bottom at each side member 13 of said sec tion, has a portion 2a whichever-laps the bottom edgeof and embraces the lower portion 1'! of said side member 13,,andsaid portion terminates, at the under side of the bottom 15, in an arm 25 projectin at 7 the inner side of said "portion 17 of said side member 13, inwardly ma arrangedto form a seat for said bottom. The arms 25 of the portions 24: of each reinforcing member are brazed, welded or otherwise secured to gethenor to the bottom 15. 1t will-be observed, therefore, that each portion 24 of each reinforcing member forms a foot adapted to rest on the floor of the room to be heated by my improved radiator or heater.

The space formed under the'bottom 15 and-between the lowerportions 1"? of the side members 10 is, of course,open at the ends of the receptacle so that air may enter said space at said ends, and *itwilhalso be observed that the bottom edge of the. portion 17 of each side member 13 isspaced upwardly from the :"lowci' extremities of, the adjacent foot-forming portions of the reinforcing members B andC so as to permit the passage of air'at said edge into said space froinbetween adjacentreinforcing members. To facilitate the supply of air to the space formed under the bottom 15 between the lower portions 17 of the side members 13, each portion 17 of each of said side members has a row'of air-inlets 26 formedht and spaced endwise of its bottom edge between the reinforcing members and secured thereto to form a fluid-tightre ceptacle, and outlet and inleth'ieans for said receptacle to permit passageof a fluid.

2. A heat-radiating device comprising an inverted-trough-shaped member .wll ioh forms the top and side walls-of saidf device,

- a second member substantially U shaped and constituting the bottom and end walls of said device and lying within the inverted-trough-shaped member and secured thereto to form a fluid-tight receptacle, outlet and inlet means for said receptacle to permit passage of a fluid, and reinforcing members spaced endwise and arranged externally of and embracing the aforesaid inverted-trough-shaped member and extending under the bottom edges of said inverted-trough-shaped member.

3. A heat-radiating device comprising an inverted-trough-shaped member w h i c 11 forms the top and side walls of said device,'

' verted-trough-shaped member and secured thereto to form a fluid-tight receptacle, outlet and inlet means for said receptacle to permit passage of a fluid, and reinforcing members spaced endwise of and embracing the aforesaid inverted-trough-shaped member and having portions thereof arranged to form seats for and to reinforce the aforesaid second member.

4. A heat-radiating device comprising a fluid-tight receptacle oblong in plan, said receptacle having outlet and inlet means permitting passage of a fluid, end walls, a member forming the side walls and top of said receptacle, said member extending be yond the end walls and bottom of the receptacle, and reinforcing members spaced lengthwise of the receptacle and embracing completely the member which forms the top and side walls thereof.

5. A heat-radiating device comprising a fluid-tight receptacle oblong in plan, said receptacle having outlet and inlet means permitting passage of a fluid, end walls, a member forming the side Walls and top of said receptacle and extending below the bottom of the receptacle and having lateral air-inlets below said bottom, and reinforcing members spaced lengthwise of the receptacle and embracing completely the member which forms the top and side walls of the receptacle.

6. A heat-radiating device comprising an inverted-trough-shaped member w h i c h forms the top and side walls of said device, a second member substantially U-shaped and constituting the bottom and end walls of said device and lying within the inverted-trough-shaped member and secured thereto to form a fluid-tight receptacle, and outlet and inlet means for said receptacle to permit passage of a fluid, the aforesaid inverted-trough-shaped member extending endwise beyond the ends of and below the aforesaid second member.

In testimony whereof, I sign the foregoing specification.
